VENTILATED GOGGLES.

Specification of Letters Patent.

Application filed April 10, 1919. Serial No. 289,121. 1

I To all whom it may concern:

Be it known that I, HARRY F. SHINDEL, a citizen of the United States,residin at Reading, in the county of Berks and tate of Pennsylvania,have invented certaln new and useful Improvements in Ventilated Goggles,of which thefollowing is a specificatlon.

My invention relates to goggles in whlch ventilatin openings areemployed in connection with meansfor baffling the admission of light andforeign matter therethrough; my object is to provide a very simple, neatand economical construction for such purpose. The invention is fullydescribed in connection with the accompanying drawing and isspecifically pointed out in the subjoined claim.

Figure 1 is an end elevation of a goggle cup showing two ventilating oenings one of which has my improved ba e plate applied thereto.

- Fig. 2 is a cross-sectional view on the line 2-2 of Fig. 1. 1

Fig. 3 shows my completely formed bafiie plate separately, and Fig. 4shows the sheet material blank from which the same is formed.

The drawing illustrates a folded and clamped sheet-material oggle cup asuch as is shown in my prior l atent No. 1,296,707 issued Mar. 11, 1919,excepting as to my present improvement applied thereto. Each of the twoventilating openings 12 b which are shown in the illustrated cup, is ofcircular form, and has a plurality of smaller apertures a 0 near itsmarginal edge; said opening and apertures being punched in thewall-forming blank. The baffle device provided for so covering thisventilating opening I) as to exclude objectionable admission of lightand foreign matter to the eye cup, is designed to effect these essentialpurposes and at the same time produce a strikingly neat appearance, withthe greatest possible economy and permanence in construction; and tothese ends it is made from a simple sheet-material punching or blank,such as is shown in Fig. 4, and which is readily formed into thecomplete device shown in Fig. 3 by means of suitable dies; said devicecomprising merely a main cover-plate portlon e, tures of the cup Wall,and having a roundlngly-turned circular edge f arranged to eX- tendtoward the cup wall and overlap the edge of the ventilating opening; anda plurality of perpendicularly. turned clamping ears g g,correspondinginnumber and spac mg with the apertures c c in the cup wall, and formedwith off-sets h k arranged to seat against said wall when the clampingears are engaged in said apertures, so as to fixedly space the coverplate therefrom when the device is ri idly secured to the cup wall byclenching the. extending clamping ears as indicated. 1

My invention as set forth provides a specifically novel constructionserving perfectly the recognized requirements as to ventilating effectwith needed protection, and also as to desired neatness of appearanceand avoidance of weightiness and bulk, with a maximum of economy andpermanence in construction.

What I claim.is

In combination with a goggle eye-cup having its wall provided with aventilating opening and a plurality of apertures adjacent said opening;a sheet-material baflle plate comprising a cover portion having a turnededge overlapping the-edge of said "opening, and spaced clamping earsextending from said turned edge through said apertures and formed withoff-sets seating Patented Nov. 25, 1919.

curved to conform with the curvaagainst said wall to space said coverportion therefrom. I

In testimony whereof I afiix my signature.

HARRY F. SHINDEL.
